General presentation

The PIC is the gateway to allow communication between a TRANE

equipment and a BMS (Building Management Systems) vendor through the

Modbus protocol over a RS232 or a RS-485 link.

The PIC handles Modbus RTU according to Reference Guide: Modicon

PI-MBUS-300 Rev. D

Modicon®is a trademark of Modicon, Inc.

Jbus®is a trademark of April.

Modbus/Jbus Considerations:

Jbus is an extension of Modbus. Jbus supports more functions than

Modbus.

• Functions supported by both Modbus and Jbus:

1, 2, 3, 4, 5, 6, 15 and 16

• Functions supported by Jbus but not supported by Modbus:

7, 8, 11, 12 and 13

Mounting and wiring

PIC mounting recommendations

To mount the PIC device:

• Select a location near the controlled equipment to reduce wiring costs

and EMC disturbance risks.

• Verify that the location conforms to the specifications below.

• Secure the controller to a 35 mm DIN rail (Use only 10/10 mm thickness

sheet) or directly mount the PIC using four M3 screws (not supplied).

1 = Screw holes

2 = DIN rail

PIC Power Supply recommendations

The PIC device is powered by 24 VAC/VDC +6V/-12V power supply. A 3-wire

quickconnect terminal (TB3) is provided for power supply connection to the

board.

To ensure the controller will operate properly, verify that the power supply

circuit is in compliance with the following circuit requirements:

To keep the PIC in accordance with the Separated Extra Low Voltage (SELV)

circuit, the transformer 'T' shall be in accordance with EN / IEC 61558-2-6.

Table 3 - Power supply recommendations

CAUTION! PIC power supply circuit MUST NOT be connected to the ground

as shown in the above illustration.The non-respect of this requirement will

damage the PIC.

CAUTION! If local electrical regulations do not allow the recommended

power supply wiring, contact your local Trane Sales Office for an adequate

solution to comply with local electrical regulations.

Note:This wiring is in accordance with IEC 60364-4-41 and national

standards which incorporate the same requirements.

Protection

The PIC device must receive power from a dedicated circuit which is

connected to a dedicated isolation screened transformer. The circuit

must be protected by a 0.5 A / 250V / Medium time lag circuit

breaker/fuse located next to it.

Recommended

wire

The AC/DC-power wiring requires three-wire cable.

The recommended wire is 1.5mm² (16 AWG) copper wire.

Standards

The AC/DC-power wiring complies with IEC or EN 60364-4-41 and

2006/95/EEC for electrical safety.

For compliance with 2006/108/EEC and 89/336/EEC European directive

for electromagnetic compatibility:

- EN 55022 level B

- EN 61000-3-2

- EN 61000-4-2

- EN 61000-4-4

Ground

Connection

The ground connection of the PIC (GND connector) MUST BE

connected to the building earth to prevent electromagnetic

compatibility risks.
